The Luxembourg Sandstone (French: Grès de Luxembourg) is a geologic formation in Luxembourg. It exists along the eastern margin of the Paris Basin. Sandstone units continuous with the Luxembourg Sandstone also occur in France. It is Early Jurassic in age. It predominantly outcrops in a belt extending through south-central Luxembourg.
Lower Jurassic sandstone of the Grès de Luxembourg Formation near Waldhof. The geology of Luxembourg is divided into two geologic regions: Rheinisches Schiefergeblige in the north, extending into the Ardennes region in Belgium, and the Oesling (also known as Islek) Zone to the north of Ettelbruck.
City of Luxembourg: its Old Quarters and Fortifications: Luxembourg City: 1994 699; iv (cultural) The city developed around a fortress built in the 10th century on an almost inaccessible rock. Due to its strategic location, it passed among great European powers several times, with the fortifications being constantly upgraded.
Luxembourg was partitioned three times, reducing its size. Having been restored in 1815 after the defeat of Napoleon, it regained independence in 1867 after the Luxembourg Crisis. Luxembourg is a developed country with an advanced economy, and has one of the world's highest PPP-adjusted GDPs per capita as per the IMF and World Bank estimates ...
The Luxembourg plateau is a large Early Jurassic sandstone plateau in south-central Luxembourg. [1] Lying mostly between 300 metres (980 ft) and 400 metres (1,300 ft), [ 1 ] it is the dominant part of the Gutland region.

The heavily fissured, more or less porous, rock strata of the so-called Luxembourg Sandstone (geologically part of the Lower Jurassic or German Lias) are laid over keuper beds that tend towards being impervious. As weathering progresses, the structure becomes unstable as a result of the undercutting of the sandstone base.
The Guttland has a lower altitude above sea level and a flatter landscape than the Éislek. Geologically, the Guttland is predominantly a large Jurassic-Triassic sandstone formation, part of the Lorrainian system; the Éislek is predominantly Devonian schist and quartz. Both are wooded, but the Éislek's forests are more numerous and thicker, a ...
